The snail collected by Dr. Hensel, and compared with Bui. 

 sus in the Malakozoologische Blatter, 1868, p. 177, is this same species 

 in less well preserved condition. It belongs, according to the sculp- 

 ture of the earlier whorls, in the immediate group of Jin/, oratus, and 

 holds a relation to that species similar to that sustained by B. accel- 

 erans Marts, toward B. valenciennesi. (Martens).
